Which corals will do battle/hurt my hammers and frogspawn

[Daniel62]

I have started a new tank that will mostly house these 2 types of corals. And I have read that certain types of corals don't play nice with each other. So who are the mortal enemies of these 2 corals.
ie zoanthids, mushroom, xeina, leather, sponges etc. Please be as specific as you can.
Thanks Daniel

Daniel,
Have you read the article about Renaming corals in this months RC mag? It mentions allelochemical interactions between leathers and Euphyllia sp.
